Strips of chocolate for decorating can be made in many lengths and widths depending on the tool you use to shave the chocolate. The easiest way to shave chocolate is to get a candy bar or block of chocolate. Let the chocolate come to room temperature or soften it in a microwave at 50% power and then use a vegetable peeler.
If you pull the vegetable peeler all along the edge, you will get strips of chocolate which will curl. If you want more of a shaved looked, just pull the peeler for a shorter distance. Keep the curls and shavings refrigerated if you’re not going to decorate with them right away.
